See Table 1. AirChek 2000 sampling time can be set up to 999 minutes from the pump keypad or up to 30 days (43,200 minutes) from a PC using DataTrac 2000 Software. During sampling, the pump LCD will display remaining run time (will count time down from a set number of minutes) when sampling time is set from the keypad. The pump LCD will show elapsed time in minutes when the pump is programmed from a PC. If run time is longer than 9999 minutes (6.8 days), the sample time displayed on the LCD will roll over to 1 after reaching Time of day in hours and minutes (12 or 24-hour clock) with AM and PM indicators Continually updated, based on corrected fl ow rate multiplied by sampling time 2

6 Performance Profile Flow Fault: Battery Pack: Charge Time: Size: Weight: RFI/EMI Shielding: Intrinsic Safety: If the pump is unable to compensate for longer than 15 seconds due to excessive back pressure, the pump enters flow fault mode. During flow fault, the pump HOLDs, the fault icon appears on the display during the length of the fault, and the accumulated run time display is frozen and retained. After 5 minutes in fl ow fault, auto-restart is attempted every 5 minutes up to 10 times.

7 Battery Operation Installing the Battery Pack To enhance battery life, SKC ships battery packs separate from the pump. Once installed, completely charge battery pack before operating pump. 1. Carefully align the battery jack on the battery pack with the battery terminal on the bottom of the pump base plate and push the battery pack into place. 2. Insert and tighten two security screws provided. 3. Charge battery completely before operating pump (see Charging the Battery Pack). Charging the Battery Pack Ensure the pump is not running. Do not operate pump while charger is attached. To charge the battery, insert the charging plug from the charger into the battery charging jack on the back of the pump. Plug the charger into a standard wall outlet. The PowerFlex Charger will fully recharge the battery in 6 hours (see Accessories on page 28 for charger). Follow charger instructions. Using a non-approved charger voids the SKC warranty. Tampering with the battery pack voids the SKC warranty and the UL Listing for intrinsic safety. Do not charge or operate pump from charger in hazardous locations. Ensure that the computer interface port is covered before and during charging. Computer Interface Port Battery Charging Jack Ensure proper orientation of charging cable before plugging it into the charging jack. Improper orientation/contact will shortcircuit the battery. See photo at right. Note the keyed side of the charging cable plug must mate with the keyed side of the pump charging jack. Inserting the plug does not take much force. If force is required, the plug is not properly oriented. Short-circuiting the battery pack will render it immediately inoperative. 4

8 Battery Operation Battery Charge Level Indicator Three bars indicate a full charge (normally appears after charging), approximately 75 to 100%. Two bars indicate that the battery is charged enough to operate the pump, approximately 25 to 75%. One bar indicates battery charge is low (charge battery), approximately 1 to 25%. Low Battery Fault No bars and a flashing outline indicate a Low Battery Fault (pump will go into HOLD, and then SLEEP mode in 10 seconds). Run time data can be displayed by pressing any button. The pump will return to SLEEP in 10 seconds. This may be repeated. When the pump stops due to a low battery and is left to stand for a period of time, one battery bar may appear. This false recovery will fall quickly if the pump is operated without recharging it. RECHARGE THE PUMP BEFORE SAMPLING. Replacing the Battery Pack Battery Replacement Notes: To retain pump history, ensure the pump has been allowed to go to SLEEP after the last run. Pump history will be lost if the battery pack or AC power (battery eliminator) is removed while the pump is running. SKC recommends that data be downloaded to a PC using DataTrac 2000 Software prior to removal of the battery or power. The first 8 program steps will be retained in memory. Programs should be reloaded using DataTrac 2000 Software after replacing the battery pack. 1. Release the battery pack by removing the two security screws located on the bottom of the battery pack. Pull the battery pack away from the pump body. 5

9 Battery Operation 2. Carefully align the battery jack on the replacement battery pack with the battery terminal on the bottom of the pump base plate and push the battery pack into place. Battery terminal Pump base plate 3. Replace and tighten the two security screws removed in Step 1. Battery jack Battery pack Use of a repaired or rebuilt battery pack voids the SKC warranty and the UL Listing for intrinsic safety. Do not charge or operate the pump from the charger in hazardous locations! Use only an SKC-approved charger and battery pack designed for the AirChek 2000 Sample Pump to ensure reliable performance and to maintain the UL Listing for intrinsic safety and the SKC warranty. Use of any device other than the approved battery pack to power the pump voids the UL Listing for intrinsic safety. For more information on battery care and maintenance, go to Battery Eliminator The Battery Eliminator is an accessory that converts alternating current (AC) to direct current (DC) from which the pump can operate indefinitely. The Battery Eliminator should be used in non-hazardous locations only. See page 28 for ordering. To use the Battery Eliminator, the battery pack must be removed from the pump (see Replacing the Battery Pack on page 5). The Battery Eliminator is comprised of two pieces, (1) a wall cube that converts AC voltage to DC voltage and (2) a power adapter that reduces DC voltage. The wall cube fits into a standard wall outlet and its plug end is inserted into the power adapter. The power adapter is fitted on the pump in place of the battery pack. Use the battery eliminator to operate the pump in non-hazardous locations only. Use of any device other than the approved battery pack to power the pump voids the UL Listing for intrinsic safety. 6

19 Calibration Flow Rate and Volume Display Flow rate displayed on the pump LCD is the flow to which the pump has been calibrated. To maintain flow as displayed, the pump automatically adjusts flow during sampling for changes in temperature and atmospheric pressure that may differ from the temperature and atmospheric pressure present at the time of calibration. The flow rate display does not change from the calibrated flow rate. The pump will fault if it is unable to maintain the calibrated flow rate. Volume displayed on the pump LCD is corrected in that it is the result of a continual calculation of corrected flow rate multiplied by sample time. Verifying Flow Rate Using a Primary Standard 1. Connect the pump inlet to the outlet of the representative sampling medium using flexible tubing. To ensure sample integrity, tubing seals tightly onto the pump inlet filter cover. Use care when removing tubing to prevent cracking or breakage of the inlet filter cover. 2. Connect the inlet of the sampling media to a primary standard calibrator using another length of flexible tubing. 3. From HOLD, press [ ] to run the pump and enter within 10 seconds. You are in User Interface Level One. SET flashes on the LCD. 4. The LCD will display a flashing flow rate from the last sample taken. If you do not wish to change the flow rate go to Step Press to increase the flow rate or to decrease the flow rate to the desired setting. 6. Press. The flashing ADJ appears on the LCD, replacing the flashing SET. The pump flow rate can now be calibrated using a primary standard calibrator. The flow rate displayed on the calibrator will change as a result of this adjustment, not the flow rate displayed on the pump. The pump will display an adjustment factor (ADJ) only. 7. Compare the flow rate from the primary standard to that displayed by the pump. If the calibrator indicates a higher flow rate than the pump, press until the pump and calibrator are in agreement (within 10 ml). If the calibrator indicates a lower flow rate than the pump, press until the pump and calibrator are in agreement (within 10 ml). 16

20 Calibration 8. Press until End appears on the LCD. Press [ ] to save flow setting and exit the User Interface. The pump will remain in RUN. Reset run time data (see page 12). 9. Place pump in HOLD by pressing [ ]. Disconnect the calibration train. Pressing [ ] will place a running pump in HOLD, and a holding pump in RUN. If a delayed start or DataTrac 2000 schedule has been programmed into the pump, it may remain in pump memory. PROG will display in the upper left corner of the pump display. To delete this program, enter User Interface Level Two, scroll to the flashing OFF, and press [ ]. 17

21 Calibration Calibration Using the CalChek Automatic Calibration Feature The CalChek automatic calibration feature is available when calibrating an AirChek 2000 Pump with a Defender Calibrator (Cat. No M). A CalChek Communication Cable (Cat. No ) is required. Optional DataTrac 2000 Software can be used to expand the documentation capabilities of this system. The CalChek feature provides two calibration options: singlepoint calibration allows setting and verifying a flow rate at a single point before and after sampling. Multiple-point (full) calibration corrects flow to a primary standard at multiple flow rates to cover the basic operational flow range of the pump. Both types of calibration bring flow to within 5%. If using a pump version below 2.59, a pump upgrade is required for the CalChek feature. Contact SKC. Do not perform single-point or multiple-point calibration until the pump has remained at ambient temperature for several hours. Single-point Calibration Using CalChek The CalChek feature provides correction at a single flow setting and takes less than one minute to complete. Use it to set the desired flow rate before sampling and to verify flow after sampling. 1. Use 1/4-inch tubing to connect the Defender Calibrator suction port to the inlet of a representative sampling medium and the outlet of the medium to the AirChek 2000 pump inlet. 2. Run the pump for 2 minutes before starting calibration. Leave the pump on. 3. Select the Defender data port: a. Press and hold the Defender power button to turn on the calibrator. b. Press the right arrow to highlight Setup; press Enter. c. Press the right arrow to highlight Preferences; press Enter. d. Press the down arrow to navigate to Data Port. e. Press the left or right arrow to toggle to SKC. f. Press the down arrow to highlight Confirm; press Enter. 4. Enter Defender calibration mode: a. Press the right arrow and then the down arrow to highlight Measure; press Enter. b. Press the right arrow to highlight Cont.; press Enter. 5. Attach the female end of the CalChek Communication Cable to the serial port (RS-232) on the back of the Defender Calibrator. 18

22 Calibration 6. Insert the male end of the CalChek Communication Cable into the data port on the pump. 7. Place the pump in HOLD by pressing [ ]. Press [ ] again to start the pump running, and enter the security code in sequence on the pump keypad within 10 seconds. You are in User Interface Level One. 8. Press or to set the pump to the desired flow rate. 9. Press on the pump keypad until CAL appears on the pump display. 10. Press [ ] to select single-point calibration CAL will appear on the pump display. During calibration, the pump will display briefly the flow rates that it is reading from the calibrator. 12. When calibration is complete, the pump display will either show End indicating a successful calibration, or it will show an error code of E4[x] (see CalChek Error Chart on page 22). Note: To remove a CalChek error code from the LCD, press. 13. Press [ ] twice to place the pump in HOLD. Disconnect the pump from the representative sampling medium and the calibrator. To ensure sample integrity, tubing seals tightly onto the pump inlet filter cover. Use care when removing tubing to prevent cracking or breakage of the inlet filter cover. 14. Allow pump to go to SLEEP. Data does not write to memory until pump has gone into SLEEP mode. Successful single-point calibration will provide an entry in the pump history that can be viewed using DataTrac 2000 Software (v or higher). If used with earlier DataTrac 2000 versions, the entry will appear as an undecipherable code; update DataTrac 2000 Software. If an error occurs during calibration, the event will not be stored in history. 19

23 Calibration Full (Multiple-point) Calibration Using CalChek This type of calibration provides flow correction across the basic operating range of the AirChek 2000 pump (750 to 3000 ml/min) in approximately 4 minutes. The operation calibrates each flow rate to a primary standard. It can also provide a record of calibration for maintenance and quality purposes if DataTrac 2000 Software is used. SKC recommends that a full calibration be performed during pump maintenance and after non-factory repairs. Full calibration clears history, run time parameters, and the Scheduler in DataTrac 2000 Software. Do NOT place sampling media in line for full calibration. Ensure the battery pack is completely charged before starting a full calibration. Do not perform single-point or multiple-point calibration until the pump has remained at ambient temperature for several hours. 1. Use 1/4-inch tubing to connect the Defender Calibrator suction port to the AirChek 2000 pump inlet. Do NOT place sample medium in line. 2. Run the pump for 2 minutes before starting calibration. Leave the pump on. 3. Follow Steps 3 through 9 from Single-point Calibration Using CalChek on pages 18 and Verify that the battery icon on the pump display shows at least two bars. If it does not, charge the battery before proceeding. 5. Press on the pump keypad 7 times to place pump in full calibration mode. 6. The Defender Calibrator will begin to automatically calibrate the pump. Initial flow measurements are taken without flow from the pump and the pump flow rate is adjusted automatically. The pump will display FCAL, CS1, and a brief flow rate. The pump will continue to display CS2, then a flow rate, CS3, then a flow rate, etc. until calibration is completed at all flow rates between 750 and 3000 ml/min. Full calibration begins at flows lower than 750 ml/min. At these lower flow rates, the calibrator piston will move slowly. This is normal; do not interrupt calibration. CalChek full calibration can be aborted by pressing [ ]. The pump will go to HOLD. 20

24 Calibration 7. When calibration is completed, the pump will go to HOLD. If the calibration was successful, the pump LCD will revert to displaying pump run time as 0. If there was failure during the calibration process, an error code of E4[x] will appear (see CalChek Error Chart on page 22). Note: To remove a CalChek error code from the LCD, press. 8. Allow the pump to go to SLEEP mode to write calibration data to pump memory. Data does not write to pump memory until pump has gone into SLEEP mode. CalChek Full Calibration Data Full calibration data can be viewed and printed by going to the DataTrac 2000 Pump Manager window and clicking on the View menu. Choose Calibration Info. This will display calibration results, pump serial number, and date of the last full calibration. A button allows this data to be printed. The printed report contains pump version, date printed, and a validation code. CalChek Calibration Data Verification in DataTrac 2000 Software This feature requires pump version 2.62 or higher and DataTrac 2000 Software version 3.62 or higher. To ensure that printed data has not been tampered with, pull down the Tools menu and choose Confirm Validation Code. Enter the data from the printed report, including the validation code. DataTrac 2000 will indicate whether the information is completely valid or if a parameter has been changed. Clearing the history will not clear full calibration data. This data can only be cleared by performing another full calibration or by obtaining more than 36 pump history records. When entering data to confirm the validation number, enter the date in the following format: mmm dd, yyyy (e.g., Aug 18, 2008) 21

26 Calibration Calibrating for Low Flow (5 to 500 ml/min) Sampling Applications Using a Constant Pressure Controller (CPC) For use with CPC and Adjustable Low Flow Tube Holders. The Constant Pressure Controller (CPC) is an accessory that allows low flow (5 to 500 ml/min) applications. In conjunction with an Adjustable Low Flow Tube Holder accessory, the CPC is used as a pressure regulator to maintain a constant 20 inches water back pressure. See Accessories on page 28. Calibrate with Adjustable Low Flow Holder, CPC, and representative sample medium inline. 1. a. For single-tube applications, set the flow rate to 1500 ml/min. b. For multiple-tube applications, the pump flow rate must be set at 15% higher than the sum of the flow rates through all tubes. Do not exceed 500 ml/min flow rate per tube for multiple-tube sampling. To set the pump flow rate, from HOLD press [ ] to run the pump and enter within 10 seconds. You are in User Interface Level One. SET and flow rate flash on the LCD. 2. The flow rate displayed is from the last sample taken. Press to increase flow and to decrease the flow to the desired setting. Press until End appears, and then press [ ] to save the change and exit the User Interface. The pump will remain running. If desired, press [ ] again to place the pump in HOLD. 3. Connect the pump inlet to the CPC outlet (the side of the CPC without a label) using a short length of Tygon tubing. 4. Connect the inlet side of the CPC (marked to sample ) to the Adjustable Low Flow Holder. 5. Label tube(s) and port(s). Insert an opened representative tube into the rubber sleeve of each port on the Adjustable Low Flow Holder. Place unopened tubes in any unused ports to seal them. 6. Loosen the brass flow adjust screw on the low flow holder. Connect the exposed end of one tube to a primary standard calibrator using another length of tubing. From HOLD, press [ ] to run the pump. 7. Turn the flow adjustment screw (needle valve) on the low flow holder until the calibrator indicates the desired flow rate. The flow rate displayed on the calibrator will change as a result of this adjustment. The flow rate on the pump LCD will remain at the previously set flow rate, showing the flow rate through the pump, not through the sample tube. 8. Repeat Steps 6 and 7 to calibrate the flow rate through each tube. Seal unused ports during calibration with unopened tubes. 9. Place the pump in HOLD by pressing [ ]. Disconnect the calibration train and replace the representative tube(s) with the tube(s) to be used for sampling. Reset the run time data to zero (see page 12). 23

27 Sampling Sampling (1000 to 3250 ml/min Constant Flow) 1. Following calibration, replace representative sampling medium with a new unexposed medium. Ensure run time data has been reset (see page 12). Protect sample pump from weather when in use outdoors. For multiple-tube sampling, seal unused holder ports with unopened tubes. 2. To begin sampling, press [ ] to run the pump. Record the start time. 3. Sample for the time specified in the method used. 4. To stop sampling, press [ ] to place the pump in HOLD. Record the stop time. 5. When sampling is complete, pump data is retained in memory for recovery. Data can be viewed on the LCD by using the button to scroll through it or on a PC using DataTrac 2000 Software. When using impingers, place an in-line trap between the pump and the impinger to protect the pump from harmful liquids or vapors. Failure to use the impinger trap voids the pump warranty. If a delayed start or DataTrac 2000 schedule has been programmed into the pump, it may remain in pump memory. PROG will display in the upper left corner of the pump display. To delete this program, see page 14 or 15. To ensure sample integrity, ensure tubing seals tightly onto the pump inlet filter cover. Use care when removing tubing to prevent cracking or breakage of the inlet filter cover. Low Flow Sampling (5 to 500 ml/min Constant Pressure) Low flow sampling requires a Constant Pressure Controller (CPC) and adjustable flow tube holder available as accessories or in the Low Flow Adapter Kit, Cat. No When sampling with the CPC accessory and multiple tubes, the volume displayed on the pump is no longer representative of the volume of flow through the tubes due to the air bypass function of the CPC. 1. Following calibration (see page 23), replace the representative tube(s) with a new unexposed tube(s). Protect sample pump from weather when in use outdoors. 2. Press [ ] to RUN the pump. Sample for the time specified in the method used. 3. To stop sampling, press [ ] to place the pump in HOLD. 24

28 Sampling Long-duration Color Detector Tubes require a special tube cover that accommodates an in-line trap tube. The trap tube protects the pump from caustic fumes that are often released from detector tubes. Closely read all precautions when using these tubes. Failure to use the necessary traps will damage the pump and void the warranty. To ensure sample integrity, tubing fits tightly onto the pump inlet filter cover. Use care when removing tubing to prevent cracking or breakage of the inlet filter cover. Use of any device other than the approved battery pack to power the pump voids the UL Listing for intrinsic safety. Flow Fault If the pump is unable to compensate for longer than 15 seconds due to excessive back pressure, the pump enters flow fault mode. During flow fault, the pump HOLDs, the fault icon appears on the display during the length of the fault, and the accumulated run time display is frozen and retained. As part of the flow fault feature, the pump attempts to restart sampling after five minutes in flow fault and continues to attempt a restart every five minutes thereafter until the restricted flow is corrected or the pump has attempted a maximum of 10 restarts. The maximum number of restart attempts may be changed using DataTrac 2000 Software. 25

29 Maintenance Replacing the Inlet Port Housing and Filter 1. Remove the three screws that secure the inlet port housing to the top of the pump. 2. Remove the inlet port housing and gasket. 3. Remove the O-ring. 4. Remove and discard the filter. 5. Insert a new filter (Replacement Cat. No. P40011). 6. Insert O-ring*. Replace the gasket. 7. Align the inlet port housing with the three screw holes and the LED. 8. Insert the three screws and tighten in an alternating fashion. Do not overtighten screws. Overtightening can crack the inlet port. * Replace with new O-ring only as needed. 26
